I actually wanted to ask some of you guys about that..... I was under the impression that bedrock under the L.A. basin was kind of deep, hard to get to and being in an earthquake zone it was a little less reliable than bedrock found in other areas where no earthquakes occurred...that's what I've heard over the years, I don't need anyone to bite my head off and be sarcastic...also.... In situations like this, when architects design towers in areas where there is no bedrock or bedrock is really deep, they create foundations that are basically like islands of bedrock within themselves and are designed to handle the weight and pressures of the buildings above and land around them. so tall buildings needing bedrock is false...not always needed.....But in terms of there being bedrock under downtown, I wasn't sure and its hard finding info about bedrock and etc for the L.A. area. ugh story of my life.

If there was ever a perfect location for a new supertall (okay, fine, a near supertall -- happy now?), this would be it. Right at the corner of a major intersection and across the street from 7th Street/Metro Center. It's great.

^^^ I think he was sarcastically referencing the people (specifically the Transbay Trolls) that keep trying to downgrade the WG because in their mind their tower is taller and they don't think the spire should count. Funny because the highest floor and roof will still belong to US Bank, highest architectural feature will go to the Wilshire.
I doubt they really mean its not supertall.

Exciting developments in the construction of the Wilshire Grand Project : The Tallest Building West of the Mississippi

The Box Columns or Starter Columns as they are also referred to, are en route to the job site from Schuff Steel in San Diego. They will begin to place each column in the footprint of the foundation starting this Monday December 2nd, 2013. Each of the Box Columns weigh 42,000 lbs; they are approximately 18 feet long/high and weigh an average of 2,333 lbs. per square foot. Very cool!
